When you are driving on a highway, you can make your trip much easier by using the cruise control feature on your car.

But you might be wondering if you can use cruise control in other situations, like when you’re driving up a hill.

Should the cruise control be used on hills?

Cruise control works best on flat or mostly flat terrain. Using cruise control on steep hills can cause the engine’s transmission to wear out faster. On descents, your vehicle might also go faster than you want it to.

Read on to find out more about how to use cruise control on hills.

Why Should I Use Cruise Control On Hilly Roads?

Is Cruise Control Bad For Your Car (1)

If you know how to use the cruise control on your car well, you may not have any trouble using it on hills. But most car experts we’ve talked to say that you shouldn’t use cruise control on hills.

On hills, you shouldn’t use adaptive cruise control (ACC) or any other kind of cruise control.

We recommend that you use your car’s brakes and accelerator to control your speed when driving up a hill.

This is important not only when going uphill but also when going downhill.

When driving uphill with the cruise control on, your car might not speed up as needed.

If this happens, your car might move much slower than other cars around you. This could be dangerous and cause an accident.

If you have cruise control on and are going downhill, your car may do the opposite and speed up very quickly, which could catch you off guard.

When this happens on a very steep downhill grade, your car will actually be going faster than the cruise control speed and the posted speed limits for the road. This also makes it more likely that you will get into a serious car accident.

When you use cruise control on hills, your car may also shift gears more quickly than it would if you didn’t use cruise control.

This gives you much less control over your car’s speed and how it handles. It also causes your engine and transmission to wear out faster, which could lead to expensive repairs.

Can Cruise Control be Used on Hills?

Since cruise control was mostly made to be used on flat roads with little traffic, it is usually not a good idea to use it on hills.

But you’re wrong to think that you can never use cruise control on hills.

You might be able to use your cruise control safely if you are going up or down a hill that isn’t too steep, has little or no traffic, and doesn’t have sharp turns or one hill after another.

In fact, you can do that, and it will save you a lot of gas.

We recommend that you turn off your cruise control if the hills you will be driving up are very steep or if the roads twist and turn a lot. This will keep you as safe as possible while driving.

Does Cruise Control Save Gas on Hills?

Is Cruise Control Bad For Your Car (3)

When going up or down hills, you can save gas by using cruise control in some situations.

If you have a high-quality cruise control in your car, the owner’s manual may say that it can handle hills that you might run into while driving.

But this might or might not be true.

Most experts agree that when driving on flat roads with cruise control, the average driver will use 15% less gas than they would without cruise control.

But when going up or down a hill, the cons of using cruise control to save gas far outweigh the pros.

If you use your cruise control on a hill, your car might either slow down too much when going uphill or speed up too much when going downhill on a steep grade.

Since you won’t have enough control of your car and the engine and transmission will be put under a lot more stress, any money you save on gas while driving uphill may be spent on repairs to your transmission and engine.

When Should Cruise Control Not be Used?

Even if you are a good driver, have a car that handles well in bad weather, and have used your cruise control a lot, there are still times when you shouldn’t use it.

First of all, we don’t think you should use your cruise control when driving in the winter, especially if the roads are snowy or icy.

If you try to use cruise control in these conditions, you’re much more likely to lose control of your car.

Also, it’s best not to use your cruise control when the roads are wet from rain when it’s hot outside.

Under these conditions, your car could hydroplane while on cruise control, which would probably cause you to crash.

Can Cruise Control be Bad for Your Car?

When you use your car’s cruise control as it was meant to be used, it won’t hurt your engine, transmission, brakes, or any other part of your car.

In fact, if you use it the right way, it might even make your car last longer.

When you use cruise control, you don’t have to use your brakes as much. This makes your engine and transmission work less hard.

Knowing how to use your cruise control can save you money in more ways than one. For example, you could save up to 15% on gas if you know how to use it.

Even though you shouldn’t use your cruise control when going up or down most hills, it can be helpful in some situations.

If the roads are dry, you won’t be meeting a lot of traffic, and you won’t be going through a place with one sharp turn or hill after another, the cruise control may make your trip easier.
